This paper presents the comprehensive study and analysis of Golumb codes used for the test vector compression and Decompression in the field of VLSI testing. The Golumb codes are targeted to minimize the size of test data, which trim down the size of memory required in ATE. This paper also gives out an idea about the design of Golumb Encoder & Decoder using VHDL for the test vectors thus achieving a good height of compression ratio. The Modified Golumb coder eradicates the drawbacks of the simple Golumb Encoder and Decoder.In order to prove its legality, the developed algorithm is simulated using the Xilinx 9.2i and Quartus software.
